2.2 Kinds of Operation
This AFM supplement does not grant approval for IFR operations to aircraft limited to VFR operations.
The GPS navigation capability of this unit cannot be used as primary navigation for IFR operations.
This system is placarded in close proximity to the GTN: “GPS LIMITED TO VFR USE ONLY”.
2.3 Applicable System Software
This AFMS/AFM is applicable to the software versions shown in Table 2.
The Main and GPS software versions are displayed on the start-up page immediately after power-on. All software versions displayed in Table 2 can be viewed on the System – System Status page.
Software Item / Software Version(or later FAA Approved versions for this STC)
Main SW Version / 3.00
GPS SW Version / 5.0
Com SW Version / 2.10
Nav SW Version / 6.02
Table 2 - Software Versions
2.4 SD Card
It is required that the SD card be present in the unit at all times.
2.5 Ground Operations
Do not use SafeTaxi or Chartview functions as the basis for ground maneuvering. SafeTaxi and Chartview functions do not comply with the requirements of AC 20-159 and are not qualified to be used as an airport moving map display (AMMD). SafeTaxi and Chartview are to be used by the flight crew to orient themselves on the airport surface to improve flight crew situational awareness during ground operations.
2.6 Terrain Proximity Function (All Units)
Terrain and obstacle information appears on the map and terrain display pages as red and yellow tiles or towers, and is depicted for advisory use only. Aircraft maneuvers and navigation must not be predicated upon the use of the terrain display. Terrain and obstacle information is advisory only and is not equivalent to warnings provided by TAWS.
The terrain display is intended to serve as a situational awareness tool only. By itself, it may not provide either the accuracy or the fidelity on which to base decisions and plan maneuvers to avoid terrain or obstacles.
NOTE
Terrain and TAWS are separate features and mutually exclusive. If “TAWS B” is shown on the bottom right of the dedicated terrain page, then TAWS is installed.
2.7 TAWS Function (Optional)
Flight crews are authorized to deviate from their current ATC clearance to the extent necessary to comply with TAWS warnings. Navigation must not be predicated upon the use of TAWS.
If an external TAWS annunciator panel is installed in the aircraft, this annunciator panel must be fully functional in order to use the TAWS system.
NOTE
Terrain and TAWS are separate features and mutually exclusive. If “TAWS B” is shown on the bottom right of the dedicated terrain page, then TAWS is installed.
2.8 Datalinked Weather Display (Optional)
This limitation applies to datalinked weather products from SiriusXM via a GDL 69/69A, FIS-B via a GDL 88, and Connext via a GSR 56.
Do not use data link weather information for maneuvering in, near, or around areas of hazardous weather. Information provided by data link weather products may not accurately depict current weather conditions.
Do not use the indicated data link weather product age to determine the age of the weather information shown by the data link weather product. Due to time delays inherent in gathering and processing weather data for data link transmission, the weather information shown by the data link weather product may be significantly older than the indicated weather product age.
Do not rely solely upon data link services to provide Temporary Flight Restriction (TFR) or Notice to Airmen (NOTAM) information. Not all TFRs and NOTAMS can be depicted on the GTN.
2.9 Traffic Display (Optional)
Traffic may be displayed on the GTN when connected to an approved optional TCAS I, TAS, TIS, or ADS-B traffic device. These systems are capable of providing traffic monitoring and alerting to the flight crew. Traffic shown on the display may or may not have traffic alerting available. The display of traffic is an aid to visual acquisition and may not be utilized for aircraft maneuvering.
2.10 StormScope® Display (Optional)
StormScope® lightning information displayed by the GTN is limited to supplemental use only. The use of the StormScope® lightning data on the display for hazardous weather (thunderstorm) penetration is prohibited. StormScope® lightning data on the display is intended only as an aid to enhance situational awareness of hazardous weather, not penetration. It is the flight crew’s responsibility to avoid hazardous weather using official weather data sources.
When the GTN StormScope® page is operating without a heading source, as indicated by the “HDG N/A” label at the upper right corner of the StormScope® page, strikes must be cleared after each heading change.
2.11 Flight Planner/Calculator Functions
CAUTION
When using the Density Altitude / True Airspeed / Winds page, all data must be entered into the calculator before the calculated data is used. Calculated data may not be correct prior to entering all data.
The Fuel Planning page uses Fuel on Board or Fuel Flow as received from an on board fuel totalizer, as entered by the pilot at system startup, or as entered by the pilot when on the Fuel Planning page. This is not a direct indication of actual aircraft fuel flow or fuel on board and those values are only used for the Fuel Planning page. The fuel required to destination is only a calculated and predicted value based on the data entered into the planner. It is not a direct indication of how much fuel the aircraft will have upon reaching the destination. Certain approach leg types will result in the fuel burn incorrectly calculated as zero.
